WIRE-WEAVING MACHINE.

Application filed November 22, 1918. Seria1 No. 263,725.

To all whom it may concern:

Be it known that we, GEORGE H. NORRIS and EDWARD "A; ERNEST, citizens of the United States, "and residents of Milwaukee, in the county of Milwaukee and State of Wisconsim'have invented new and useful Improvements in WVire-VVeavin'g Machines, of which the following is a descriptiom reference being had to theaccompanying drawings, which are a part of this specification.

The invention relates to a machine for weaving 'wire fabric, more particularly mesh, and consists of the various parts and combinations of parts hereinafter described and shown in theaccompanying drawings in which: a

Fig. 1 is a side view of the machine embodying the invention; Fig. 2 is .a plan view thereof; Fig. 3 is a front end view; Fig. 4 is a detail side view; 5 and 6 are detailed views of the completed wire.

Referring to the drawings, the numeral 5 designates generally the frame of the machine which includes channel uprights 6,

the channels of which are divided into guide channels 7 and 8 by bars 9. A weaving frame 10 is slidably mounted in the channel 7 and a similar weaving frame 11. in the channel 8. Each weaving frame includes a plurality of spaced apart vertically dis posed members 12 having alined apertures 13 therein, and the vertically disposed members 12 of the frame 10 are staggered with respect to those of the frame 11 and the apertures 13 of these frames are also spaced apart. The frames 10 and 11 are'not dlsposed in alinement, but in either of their extreme positions a part of one of the frames is disposed above and apart of the other frame below that of the other as shown in Fig. 1, and means are provided for vertically reciprocating these frames with respect to each other comprising levers 14 pivotally connected intermediate their ends to a transversely extending rod15 and having one of their ends pivotally connected to frame 10 by links 16 and the other of their ends pivotally connected to frame 11 by links 18. The levers 14 are given a rocking movement by means of connecting rods 19 pivotally connected at one of their ends to the end of the levers and pivotally connected at their other ends to cranks 20 on a shaft 21 which is driven from the drive shaft 22 through gears 23 and 24, the drive shaft 22 being connected up to a source of power through a pulley 25 adapted to be secured :to rotate with said shaft 22 by means of a coils is not straight, but is bent into a wavy line having alternately curved portions as shown at 31 in Fig. 5. The wires from the coils run lengthwise of the machine and are led over a flat guide 32, and arejthen threaded through the eyes or apertures 13.

of the weaving frame '5, alternate wires passing through the apertures 13 in the frame 10 V and the other wires passing through the apertures in the frame 11 with the result thatadjacent wires, such as 33 and 34 in Fig,

1 wili be spaced apart when the weaving frames are moving to or are intheir upper or lower positions. I 7

After passing throughthe weaving frame the-wires pass through the openings 35in a latticed frame 36 which is carried by levers 37 pivotally mounted at ftheir lower ends upon the frame of the machine. This latticed frame is reciprocated back and forth during the weaving operation by means of links 38 pivotally connected at one of their ends to the upper portion of the le vers 37 and at their other ends to cranks 39 carried by the shaft 22.

In addition to serving as guides for the lengthwise extending wires this latticed frame serves to push the cross wires 40 into place between the diverging: adjoininglengthwise extending wires. that 1s after the operator runs a cross wire through the space 41 in the spread apart wires of Fig. 1 the latticed frame moves forward and pushes this wire into position so that when the weaving frames move past each other the cross wire is secured in' place. The cross wires 40 are also of the same wavy formation as the wires 31 and are stacked in-a. trough 42 near the machine within easy reach of the operator.

The completed woven wire is removed from the machine and the lengthwise extending wire held in tension by means of toothed wheels 43 and a. support 44, the toothed wheels being mounted upon a shaft 45 journalled in brackets 46 on the machine frame This shaft 45 is given a step by step rotation by means of a ratchet wheel 47 and a spring pressed pawl 18 carried by the frame 36 and engageable with said ratchet on the forward movement of the frame. The ratchet is prevented from turning back by a holding pawl 49. To prevent operation of the feeding mechanism a stop 50 on a lever 51 is moved into the path of the pawl 48 so as to prevent its engaging the ratchet 47, the lever being pivotally connected intermediate its ends to the frame and pivotally connected at its lower end to a link 52 and at the upper to the frame. The depression of the treadle 55 by the operator moves said stop out of the path of the pawl 48 and this is done by the operator immediately after a cross wire has been inserted between the spread apart lengfihwise extending wires.

A stop plate 56 is secured to one of the uprights 6 and is in the path of the inserted cross wires so as to limit the inward movement of these wires.

With the construction above described the frames 10 and 11 carrying alternate lengthwise extending wires reciprocate back and forth to permit of the insertion of the cross wires between the separated lengthwise extending wires and retain said cross wires in place and the completed fabric 57 is removed from the machine by the wheels 43.

What we claim as our invention is:

1. In a wire weaving machine having a reciprocating reed frame, the combination of a support including a substantially horizontally disposed bar over which the wire may be drawn, a shaft journaled in said support, a plurality of toothed wheels on saidshaft directly above said bar, said shaft being so positioned and said wheels being of such diameter that their teeth project through the meshes of the wire and rotate close to said bar when said shaft is rotated to provide positive engagement with said wire meshes, a ratchet wheel on said shaft, a holding pawl associated with said ratchet, and a driving pawl mounted on said reed frame and adapted to advance said ratchet one step each time the reed frame reciprocates, for the purpose, described.

2.
